Boiler Installation

Replacing an aging conventional boiler with a modern high efficiency condensing boiler could immediately make a saving of up to 40% on your heating bills which in turn helps reduce your carbon foot print. Older types of system may convert only 60-70% of gas usage in to actual heat, whereas modern condensing boilers can have a near 100% fuel efficiency conversion. We can recommend the best system for you and your budget.

Condensing Boilers

By converting approximately 88% of fuel into heat the condensing boiler is the most efficient of them all, wasting the least energy. Condensing boilers are available as both conventional or combination units. A conventional boiler burns fuel in a combustion chamber surrounded by a water jacket. This heats the water, which is then circulated around the heating system. Unfortunately, much of the heat produced by the burning of the fuel is either lost to the surrounding air or disappears up the flue. Condensing boilers basically utilise the heat not recovered by the main heat exchanger and makes effective use of it by reducing the temperature of the flue gases to a point where water vapour produced during combustion is "condensed out", releasing latent heat that would otherwise escape up the flue.

Condensing Combination Boiler

Combination boilers do the work of both a central heating boiler and a hot water cylinder and they are compact (usually wall hung in the kitchen) - which means you either have more space in your airing cupboard, or you don't need one at all. Installation costs may be lower and fitting is often less disruptive than with a conventional boiler. However, because the hot water heats on demand it runs more slowly - which means it takes longer to run your bath. Combi boilers are popular in properties where space is limited because they negate the need for hot and cold water tanks. All combination boilers installed by Hot Tap are SEDBUK band A rated.

System Boiler

System boilers eliminate the need for a cold water feed tank in your loft by heating water straight from the mains, like a combi boiler. However, system boilers keep the hot water storage tank used by regular boilers and usually found in your airing cupboard. They are a sort of middle ground between the two boiler systems.

Open Vent Boilers

These are generally used in conjunction with a hot water cylinder and loft tanks. Available for oil, gas and LPG, floor standing or wall mounted with a large range of flueing options. External oil fired conventional boilers are also available.
